想用dotnetOpenAuth请求gmail授权

Question

我用dotnetOpenAuth。我想向用户的gamil请求授权。

我需要先使用openId吗？

找不到像样的tutorail。谁能帮忙？

尝试此代码unsuccesfully。反正我不似乎要求在身份验证请求Gmail的范围，所以我很困惑

public void PrepareAuthorizationRequest(Uri authCallbakUrl) 
{ 
    var consumer = new WebConsumer(GoogleConsumerConsts.ServiceDescription, mConsumerTokenManager); 

    // request access 
    consumer.Channel.Send(consumer.PrepareRequestUserAuthorization(authCallbakUrl, null, null)); 

    throw new NoRedirectToAuthPageException(); 
} 

public ProcessAuthorizationRequestResponse ProcessAuthorizationRequest() 
{ 
    ProcessAuthorizationRequestResponse response; 
    // Process result from the service provider 
    var consumer = new WebConsumer(GoogleConsumerConsts.ServiceDescription, mConsumerTokenManager); 
    var accessTokenResponse = consumer.ProcessUserAuthorization(); 

    // If we didn't have an access token response, this wasn't called by the service provider 
    if (accessTokenResponse == null) 
     response = new ProcessAuthorizationRequestResponse 
         { 
          IsAuthorized = false 
         }; 
    else 
    { 
     // Extract the access token 
     string accessToken = accessTokenResponse.AccessToken; 
     response = new ProcessAuthorizationRequestResponse 
     { 
      IsAuthorized = true, 
      Token = accessToken, 
      Secret = mConsumerTokenManager.GetTokenSecret(accessToken) 
     }; 
    } 
    return response; 
} 

private string Test2() 
{ 
    // Process result from linked in 
    var google = new WebConsumer(GoogleConsumerConsts.ServiceDescription, mConsumerTokenManager); 
    // var accessToken = GetAccessTokenForUser(); 
    var accessToken = String.Empty; 

    // Retrieve the user's profile information 
    var endpoint = GoogleConsumerConsts.GetGmailFeedsEndpoint;// new MessageReceivingEndpoint("http://api.linkedin.com/v1/people/~", HttpDeliveryMethods.GetRequest); 
    var request = google.PrepareAuthorizedRequest(endpoint, accessToken); 
    var response = request.GetResponse(); 
    return (new StreamReader(response.GetResponseStream())).ReadToEnd(); 
}

不，你并不需要使用OpenID的，如果你只是想访问用户的Gmail。 OpenID适用于您想要验证用户的情况。 OAuth用于访问用户数据。

您需要在您的授权请求中包含scope参数，如此问题所述：Adding scopes to OAuth 1.0 authorization request with DotNetOpenAuth。
